Let’s see, light bulbs like this are LED energy-saving lamps. In fact, their faults are very small, and they can be used again after simple repairs. It would be a pity to throw it away.

Let's connect it to the electricity first and check it. It is indeed off, and it is broken. First, we need to unscrew the light bulb. Then, we disassemble it and take a look at the light bulb first.

The shell has no screws, we only need to press it around this circle, and the shell will fall off, after pressing it, we will pull it off, and after taking it apart, let’s take a look at the yellow little ones inside the lamp. Cube, it is the lamp bead.

Take out a small tool, we use it to short-circuit the lamp post, find out which lamp post is broken, and this lamp post is broken, then we unscrew the lamp, and put the broken lamp post on us Cut it off.

Then use solder wire, we solder the two sides of the lamp bead to it. Then we charge it up and try it out to see if it turns on, and then there is no problem. Finally, we can install the protective cover again.";s:6:"filter";b:1;s:6:"visual";b:1;s:11:"panels_info";a:6:{s:5:"class";s:14:"WP_Widget_Text";s:4:"grid";i:0;s:4:"cell";i:0;s:2:"id";i:0;s:9:"widget_id";s:36:"f8a6d814-cbbb-4315-9942-5e89b427cd0d";s:5:"style";a:2:{s:27:"background_image_attachment";b:0;s:18:"background_display";s:4:"tile";}}s:22:"so_sidebar_emulator_id";s:14:"text-390210000";s:11:"option_name";s:11:"widget_text";}i:1;a:7:{s:5:"title";s:86:"Why does the led corn light have a row that sometimes lights up and sometimes doesn't?";s:4:"text";s:1643:"There are eight reasons why there is a row of led corn lights that are sometimes on and sometimes not on:
<ol>
 	<li>The packaging protection of the LED corn bulb lamp is not perfect, causing the lamp beads to be damaged due to impact during transportation.</li>
 	<li>The solder joints of the LED corn bulbs have weak solder joints, and the vibration during transportation causes the solder joints to fall off and cause the light strip to not light up.</li>
</ol>
&nbsp;
<ol start="3">
 	<li>The amount of solder is small, and the solder joints are easy to fall off</li>
</ol>
&nbsp;
<ol start="4">
 	<li>The quality of the solder is not good, and the solder joints of the LED flexible light strip are prone to brittle cracks and falling off during the bending process</li>
</ol>
&nbsp;
<ol start="5">
 	<li>The bending angle is too large during installation, causing the solder joints of the LED flexible strip to separate from the copper foil, resulting in no light</li>

<ol start="6">
 	<li>Excessive extrusion of the product during installation, resulting in damage to the chip of the LED flexible light strip or deformation of the solder joints and failure to light up</li>

 	<li>The solder resist layer of the circuit board is too thick, and the solder and the circuit board cannot be completely fused together during soldering, which is also a phenomenon of virtual soldering.</li>

<ol>
 	<li>The wattage will be marked on the led lamp, but the marked wattage is not the actual wattage. Because the lamp beads of the LED lamp are special, it needs to be equipped with a separate power supply to supply power, so the efficiency of the power supply cannot be 100%. .</li>
 	<li>For example, if the power of a light source is 3w, the power supply efficiency is 75%, and the actual light source is 4w, so there are two standard methods of 3w and 4w. We need to look at its wattage, we can look at the spiral pattern of the light bulb, there will be a row of numbers on it indicating how many watts it is.</li>
